How Many Watts Is A Fast E-Bike?

Your e-bike speed is very important because it determines where you can go and if you can climb steep slopes or not. Since the e-bike's speed is reliant on the wattage of the motor, how many watts is a fast e-bike?

In this post, we show you the top speed of e-bikes at different wattage levels. We also reveal the best e-bike speed to go for and why.

Let’s get to it.

How Does My E-Bike Watt Affect Its Speed?

Simply put, the e-bike wattage measures the power capacity of your motor and your motor determines the speed, torque, and acceleration of the electric bike. The higher the e-bike's wattage, the more powerful the motor would be, and the faster the e-bike will go.

To fully understand how e-bike watt affects speed, you need to know how your e-bike moves. When you pedal your e-bike, the motor generates power to spin the rear wheel and make you go faster. This feature is called the pedal-assist.

How fast the e-bike can go depends on how much power the motor can generate for the wheels while you pedal. Since the wattage measures the power capacity of the motor, you can see why it’s an important variable to consider when it comes to e-bike speed.

Asides from the increased speed, a higher wattage will also allow you to carry more weight on the bike and go through terrain many other bikes can’t. However, a higher wattage will burn through your battery power quickly. So, if you are going for an e-bike with high wattage, ensure it has a large capacity battery too.

Since that’s settled, let’s check out the top speeds of e-bikes at different wattages.

How Fast is a 250 Watt E-bike?

A 250W electric bike can reach a max speed between 10mph and 15mph when full throttle is activated.

With a 250W e-bike, you’ll need to generate more pedaling power when climbing steep slopes and hills because the speed of the bike will automatically drop as you ascend. You might also need to carry the e-bike across bumpy and hilly paths since the motor can’t generate enough torque to navigate such terrain.

25OW e-bikes are considered legal in many states because the top speed isn’t dangerous and the motor automatically shuts off power when the bike approaches speed levels around 15mph.

How Fast is a 500-Watt E-Bike?

A 500W electric bike motor can generate a top speed of around 20mph when full throttle is activated. This speed allows the rider to climb slopes and steep hills with minimal effort. The motor is also powerful enough to propel the e-bike forward without pedaling, making it possible to enjoy a relaxing cruise.

The Macfox X1 all-terrain e-bike is equipped with a 500W motor that generates up to 65 newton meters of torque and a top speed of over 15mph.

How Fast is a 750-Watt E-Bike?

A 750W e-bike motor can generate a top speed between 20mph and 28mph when in full throttle mode. This speed level will take you up steep slopes and inclines with no pedaling power required. E-bikes that have a 750W motor are often heavier and bigger than regular e-bikes.

The Macfox X2 off-road electric bike is designed with a 750W brushless motor that can reach a peak power of 1000W. When full throttle is activated, the Macfox X2 can exceed speeds of 20mph.

How Fast is a 1000-Watt E-Bike?

A 1000W e-bike motor will generate a top speed between 30mph and 35mph. At this speed, you can climb inclines and even navigate bumpy terrain easily, but the e-bike battery will wear out quickly.

Mountain bikes and other professional e-bikes are equipped with a 1000W motor to give them enough speed to go up hills and climb over obstacles.

How Many Watts is a Fast E-bike?

This depends on what you term a “Fast E-bike.” In many states, the legally-permitted top speed for an e-bike shouldn’t exceed 28 miles per hour. A 750W e-bike motor will generate this speed level easily.

If you need an e-bike to commute within your town, run errands, and ride from home to school or work daily, a 250W e-bike is fast enough. You’ll cruise above 10 miles per hour and at this speed, your e-bike is allowed on street curbs, bike paths, and roadsides. You can up the speed to 15mph when you are on the road.

If you are a professional cyclist, either a mountain or cross-country biker, you’ll need a faster e-bike which means more wattage. You need the increased speed to tackle steep slopes and climb over obstacles without any hassle. In this case, a 750W e-bike like the Macfox X2 is fast enough.

Does E-Bike Watt Affect Range?

E-bike watt doesn’t affect the range directly. Your e-bike range or mileage is determined by the battery capacity and not the motor. While the motor’s capacity in wattage (W) influences how fast the e-bike can go, the battery capacity in watt-hours (Wh) determines how far you can go.

If you want to ride for long distances, you need a bike with a powerful e-bike battery. However, if your electric bike has a powerful motor but a weak battery, the motor will exhaust the battery power quickly, leaving you with a limited range.

Final Words

Here is the bottom line – your e-bike speed depends on how powerful the motor is and you can measure the motor’s power capacity in watts. So, a 750W electric bike will give you more speed and overall better performance than a 250W e-bike motor.

While fast e-bikes can be very thrilling and addictive, you should know the e-bike laws in your resident state before buying one. In many states, you aren’t allowed to ride an e-bike that can go over 20mph.

As a beginner, you should start with a 250W or 500W e-bike motor. The higher capacity motors should be left for experienced professionals. That said, the Macfox X1 and Macfox X2 will give you more than enough power and speed to ride anywhere you want in style.

FAQs

How many watts is a fast e-bike?

A 750-watt e-bike is considered fast, reaching speeds between 20 to 28 mph. Higher wattages, such as 1000 watts, can achieve speeds of 30 to 35 mph.

Does e-bike wattage affect range?

E-bike wattage does not directly affect range. The range is determined by the battery capacity, measured in watt-hours (Wh). A more powerful motor can consume battery power faster, reducing the overall range.

What is the best e-bike speed to go for?

The best e-bike speed depends on your needs and local regulations. In many states, the legally permitted top speed for an e-bike is 20 mph. A 250-watt e-bike is fast enough for commuting, while higher wattages like 750 watts are suitable for professionals or off-road enthusiasts.
